Water-turbine generator set speed measuring device

Abstract

The invention provides a water-turbine generator set speed measuring device, relates to the field of generator set speed measurement, and solves the problems that automatic locking cannot be realizedduring adjustment, a locking structure is usually manually driven to lock after adjustment, and the operation is relatively tedious, an adjusting structure is poor in protection performance, collisionprotection cannot be achieved, and burrs are likely to be generated after a hard object collides with a sliding structure to influence the sliding quality. The water-turbine generator set speed measuring device comprises a fixing seat structure. The top end face of the fixing base structure is rotationally connected with a gear A. The telescopic arm body is further fixedly connected with a protective cover through a bolt, the protective cover is of a concave structure, and therefore the phenomenon that the top end face, the left end face and the right end face of the telescopic arm body are impacted by hard objects to deform to cause sliding blockage can be prevented. The protective cover is slidably connected into the sliding groove B, and the inner contour of the sliding groove B is larger than the outer contour of the protective cover, so that sliding is not affected when the protective cover slightly deforms.

Description

technical field [0001] The invention belongs to the technical field of speed measurement of generator sets, and more specifically relates to a speed measurement device of a hydroelectric generator set. Background technique [0002] A turbine generator refers to a generator that uses a water turbine as the prime mover to convert water energy into electrical energy. When the water flows through the water turbine, the water energy is converted into mechanical energy, and the rotating shaft of the water turbine drives the rotor of the generator, which converts the mechanical energy into electrical energy and outputs it. It is the main power equipment for generating electric energy in hydropower stations, and it needs to measure speed regularly during use. [0003] For example, the application number: CN201320576215.9, the utility model provides a speed measuring device for a generator set, a speed measuring device for a generator set, including a base, an engine installed on th...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a speed measuring device of a hydroelectric generator set to solve the existing problem that the existing speed measuring device cannot realize automatic locking during adjustment, and the locking structure is often manually driven to lock after adjustment. , the operation is relatively cumbersome; moreover, the adjustment structure on the existing speed measuring device has poor protection, and it cannot achieve collision protection. When fixing, the protective protrusions are mostly one-way long strips, and the stability is poor after fixing
